APR - ECU Upgrade - Audi 5.2L FSI Gen 2 - 2015+ Audi R8, Lamborghini Huracan
Please note that vehicle must be present at one of our shops in order to install this upgrade.
APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 5.2L FSI V10!
APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the 5.2L FSI V10 engine. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possible through APR’s optimization of the factory engine management system to take full advantage of the engine’s capabilities, without needing any end user adjustment. The software loads to the factory ECU through the OBD-II port, resulting in a clean and headache-free install.
APR ECU Upgrade Options
APR’s ECU Upgrades support various octanes without the need for any hardware modifications. Each upgrade is fully compatible with an upgraded intake, exhaust, or other minor bolt on modifications.
APR Stage I ECU Upgrade
The APR Stage I ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications, and produces 618-619 HP with 417-419 FT-LBS of torque. Gains as high as 24 HP and 16 FT-LBS of torque are available throughout the power band, making the vehicle exceptionally quicker in all scenarios. To get more power, the vehicle can be outfitted with an upgraded intake, exhaust, or other minor bolt on modifications without requiring any new modification to the ECU.
APR Stage I E85 ECU Upgrade
The APR Stage I ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications, and produces 650 HP with 435 FT-LBS of torque. Gains as high as 49 HP and 36 FT-LBS of torque are available throughout the power band, making the vehicle exceptionally quicker in all scenarios. To get more power, the vehicle can be outfitted with an upgraded intake, exhaust, or other minor bolt on modifications without requiring any new modification to the ECU.
Please note, this is not a full flex fuel program. In this mode the engine is only designed to work on E85, as found directly at the pump, including both summer and winter blends from E60-E98. Using traditional pump fuels in this mode may result in engine damage. Do not manually blend with traditional pump gasoline (87, 91, 93 (R+M)/2, etc) or race fuels. Transmission software is required to achieve power figures past the factory redline when not in manual mode.
Please note, transmission software is required to achieve power figures past the factory redline when not in manual mode.

| Reported wheel figures measured on APR's in house Mustang Dynamometer with a US Spec LP610, using SAEJ1349 correction and an average of multiple runs. Crank figures are estimated based on the measured wheel figures. Results may vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications. For the best results, APR recommends removing the intake snow screen. - Please note, transmission software is required to achieve power figures past the factory redline when not in manual mode. | |||||

APR ECU Upgrade Included Features
APR World Class Calibration Expertise
Tuning 101:
The 5.2L FSI V10 engine uses two Bosch MED17 ECUs for engine management. Basically, it’s a computer that tells the engine how to operate. Tuning software, like the APR ECU Upgrade, tells the engine how to make more power. It does this by optimizing the cam shaft positions, adjusting the air/fuel ratio, advancing ignition timing, and more.
A Better Engine Management System:
The 5.2L FSI V10's ECU is incredible. Without the driver knowing otherwise, the ECU makes intelligent adjustments to the engine’s operations to keep it running smoothly. Unlike ECUs found in many other makes and models, when properly tuned, the ECU eliminates the need for custom tuning to maximize output, even when weather conditions change dramatically.
How APR Differs from the Competition:
The ECU is powerful, but extremely difficult to master. Without mastery, the ECU must be simplified, removing what makes it so desirable. The result is an incomplete product that often requires end user adjustment to maximize output in limited scenarios. On the contrary, APR’s Engineers spent years mastering the ECU to unlock its full potential. With complete access to the thousands of maps, tables and variables within, as well as a high-level understanding of how it works, APR’s Engineers were able to take advantage of everything the ECU has to offer. Power is maximized in nearly all scenarios, eliminating the need for end user adjustments. High performance operational modes are enabled and calibrated to deliver smooth daily driving, with a snappy and responsive throttle during moments of spirited driving. Lastly advanced high-output protection routines are enabled, allowing the ECU to make constant adjustments to airflow and fuel to cool and protect the engine, all without the driver knowing otherwise.
Acceleration Enhancements:
Beyond horsepower and torque enhancements, APR’s Calibration Engineers were able to increase the acceleration rate of the vehicle through other calibrations changes. Ignition delay is reduced resulting in a more responsive pedal without altering overall throttle sensitivity. Furthermore, throttle lag commonly noticed at slow speeds and while reapplying throttle has been reduced.
Speed Limiter:
APR’s ECU upgrade increases the vehicle's top speed limiter for blistering sprints around the track or across the Autobahn without the speed limiter shutting down the fun.
Left Foot Braking:
APR's Left Foot Braking feature allows more control over the vehicle’s throttle. The factory equipped vehicle's throttle input is disabled while pressing the accelerator and brake at the same time. Left Foot Braking, a common motorsport driving technique, allows the driver complete control over the vehicle’s throttle and braking system, which may give the vehicle the edge it needs at the track.
Increased Rev Limiter:
We've increased the redline, which translates to a much quicker vehicle with an even larger powerband.
Increased Fuel Economy:
APR’s Calibration Engineers paid close attention to several parameters directly related to fuel economy, especially while cruising at highway speeds. Depending on driving style and fuel quality, better miles per gallon may be achieved.
